Molecules star in holographic 3-D movies

In the microscope, a laser beam illuminates the sample. Light scattered by the sample creates an interference pattern that is magnified and recorded. Then measurements of the particle’s position, size, and refractive index are obtained.

NYU (US)–A new technique for recording three-dimensional movies of microscopic systems, such as biological molecules, through holographic video has the potential to improve medical diagnostics and drug discovery. Continue…
